Abstract: Abstract In the present work we studied the room evacuation problem using the social force model introduced by Helbing and coworkers. The ‘faster is slower’ effect induced by increasing desired velocities was analyzed. A steady state version of the problem was implemented by reinserting outgoing pedestrians into the room. It shows that, from a macroscopic point of view, the optimal evacuation efficiency correspond to the state at which the difference between the average system desire force minus the average system granular force is maximum.
